Gastech PSA Oxygen Generator Technology:  

Oxygen is separated from air using unique zeolite ceramic molecular sieves.

Dry, oil free air at ambient temperature and elevated pressure is passed through vessels (adsorbers) containing molecular sieve. The sieve holds on to (adsorbs) nitrogen molecules in preference to the oxygen molecules, thus separating oxygen from air. The nitrogen molecules are released (desorbed) from the sieve when the pressure in the adsorber is reduced, thus making the sieve fresh again (regeneration). Typically two vessels are employed for continuous supply of oxygen. The entire cycle is microprocessor controlled and no operator attention is required for normal operation.

The only running cost is electricity. There are no other costs such as rentals for cylinders/tanks, transportation, taxes, deposits. No manpower is needed to procure, load, unload, connect and disconnect heavy high pressure cylinders. Risk of running out due to unpredictable deliveries is eliminated.

Gastech Oxygen Generators have the lowest power consumption and come equipped with dryers as standard equipment. Gastech Oxygen generators are available for industrial and medical applications, in standard and custom made sizes. The specifications such as oxygen delivery pressure and purity are selected to match customers individual requirements.
